Fermoselle
Fermoselle stands above the deep valley of the Duero on the Portuguese frontier. Alfonso IX of León granted the town and its castle to the bishop of Zamora in 1205, establishing an episcopal lordship that lasted for centuries. During the Revolt of the Comuneros, Bishop Antonio Osorio de Acuña made Fermoselle one of his chief strongholds. It was among the last rebel places to fall, in June 1522; the castle and walls were subsequently ordered dismantled as punishment.
